Hi guys,

I'm currently working with Python and sockets, and I've had a strange problem for a few days now.

Basically the idea is to:

1) Set up tun device
2) Route packets to that device
3) Read packet from there
4) Send that packet to eth0

My script "works" now, like I it does all those things that I mentioned. The problem is, I can't get any response from the system to my packets. If I for example test script with ping, wireshark shows that packets that I send are valid but system won't send any response.

The script with some comments is here: http://phew.pastebin.com/m2b3041dd

I have no idea if I'm doing something totally wrong, or if there is some strange feature in kernel that I just don't know.

Thanks,

Antti
